Damage and casualties

Within the epicentral area, 3,250 people were killed. Eighty-eight villages in the region were damaged or destroyed, along with damage at Bojnourd. Aftershocks occurred for more than four years after, including one in July 1929 that killed several more people, before finally subsiding in 1933. Fifty-seven diverse locations reported damage, including casualties in Ashgabat, Turkmenistan. Surface faulting occurred along the Baghan-Germab fault for a length of 50 kilometers (31 mi). [5]

At least 10,000 people were killed, making it one of the deadliest in its decade. The tremor caused between US$5 and $25 million in damage, felt over an area of 8,781 km2 (3,390 sq mi). In Hanoi, North Vietnam, almost 483 km (300 mi) from the epicenter, victims left their homes as the rupture rumbled through the city.

The earthquake, which was among Iran's largest, measured 7.1 on the moment magnitude scale and had a maximum Mercalli intensity of IX (Violent). A damaging foreshock occurred fifteen hours prior to the main event and served as a warning to the people that felt it strongly. Reports from seismologists and seismological organizations indicate that up to 3,000 fatalities may have occurred in northwest Iran and southeast Turkey.

<span class="mw-page-title-main">1931 Valentine earthquake</span> Most powerful earthquake in Texas history

In the early morning hours of August 16, 1931, a powerful earthquake occurred in West Texas with a maximum Mercalli intensity of VIII (Severe). Estimates of its magnitude range between 5.8–6.4 mb, making it the most powerful earthquake ever recorded in Texas history. Its epicenter was near the town of Valentine, Texas; there, the earthquake caused damage to many homes and buildings. The earthquake may have been caused by movement along oblique-slip faulting in West Texas, the most seismically-active region in the state. Shaking from the earthquake was perceptible within a 400 mi (640 km) radius of the epicenter, affecting four U.S. states and northern Mexico. Several foreshocks and aftershocks accompanied the primary temblor, with the aftershocks continuing until at least November 3, 1931. The main earthquake caused no fatalities, though several people sustained minor injuries; the damage in Valentine amounted to $50,000–$75,000.

The 2000 Turkmenistan earthquake took place at 8:11 p.m. Moscow Time on December 6 and had a magnitude of 7.0. The intensity of the earthquake reached VII at its epicenter, and IV at the Turkmen capital of Ashgabat. The epicentre was located approximately 25 kilometers north of the city of Balkanabat and 125 kilometres southeast of Türkmenbaşy. There were unconfirmed reports that the quake killed up to 11 people and injured 5 others.

The 1893 Quchan earthquake occurred at about 19:30 local time on 17 November.

The 1979 Ghaenat earthquakes were a series of large earthquakes in Qaen County, Khorasan Province, northeast Iran, near the Afghanistan border. The first mainshock, known as the Korizan earthquake with a surface wave magnitude (Ms ) of 6.6 and moment magnitude (Mw ) of 6.8, struck on November 14, while the Ms  7.1 or Mw  7.2 Koli-Boniabad earthquake struck on November 27. The two mainshocks were assigned a maximum Modified Mercalli intensity of VIII (Severe) and X (Extreme), respectively. The earthquakes caused extensive damage throughout northeastern Iran, killing an estimated 297 to 440 people and left at least 279 injured.

The 1997 Bojnurd earthquake occurred on 4 February at 14:07 IRST in Iran. The epicenter of the Mw 6.5 earthquake was in the Kopet Dag mountains of North Khorasan, near the Iran–Turkmenistan border, about 579 km (360 mi) northeast of Tehran. The earthquake is characterized by shallow strike-slip faulting in a zone of active faults. Seismic activity is present as the Kopet Dag is actively accommodating tectonics through faulting. The earthquake left 88 dead, 1,948 injured, and affected 173 villages, including four which were destroyed. Damage also occurred in Shirvan and Bojnord counties. The total cost of damage was estimated to be over US$ 30 million.

The 1977 Naghan earthquake struck Chaharmahal and Bakhtiari province in Iran on April 6 at 13:36 UTC. The earthquake measuring 6.0 Mw  occurred at a depth of 15 km (9.3 mi) and had a maximum Modified Mercalli intensity of VIII (Severe). More than 2,100 homes were destroyed and at least 348 people were killed.

It had a moment magnitude of 6.6 or 7.1 (Mw ), focal depth of 15 km (9.3 mi), and maximum Modified Mercalli intensity of IX (Violent). It devastated many communities in the Alborz Mountains and caused an estimated 1,500 fatalities. Damage was estimated at US$25 million.

The 1947 Dustabad earthquake, also known as the Charmeh earthquake, occurred in South Khorasan Province of northeastern Iran on 23 September.
